Investing in the Ecosystem preserve

Tue, Dec 01, 2015

In vernal pools frogs swim, while a barred owl dutifully keeps watch overhead. Nearby, wild turkeys forage under towering maples. In tall grass a mother grey fox trots to her kits, passed by the fluttering speed of a defensive red-winged blackbird.聽

On the other side of the woods, students bustle in and out of classes and residence halls, making their home just steps from the natural wonders of the 100-acre聽. And while the creatures in the preserve remain blissfully unaware, their human counterparts on campus are celebrating a recently secured $500,000 grant for the preserve and its education hub, the Bunker Interpretive Center.聽

The half million in financial support comes from The Harry A. & Margaret D. Towsley Foundation based in Midland, Mich. Among other causes, the family foundation invests in education, natural sciences and conservation鈥攁 legacy furthered by this commitment to Calvin. Paid over five years, the grant will support land management and educational programming.

The preserve, founded in 1985, and the interpretive center, completed in 2004, have collectively welcomed tens of thousands of visitors to campus. Guests take advantage of educational elementary school programs (more than 32,000 students),聽聽(over 700 participants) and open access trails (about 6,000 guests annually).

鈥淭his is a place that鈥檚 very open to the public, and that鈥檚 how we want it,鈥 said Megan Berglund, director of foundation relations and grants. 鈥淭his commitment to making the preserve open to the community is one thing that interested the Towsley Foundation.鈥 聽

In addition to outside guests, nearly 20 Calvin programs study or research in the preserve annually and, over the years, more than 600 students have been employed at either the preserve or the interpretive center.

鈥淢entoring and providing Calvin students with hands-on work experiences that complement what they learn in class is a large part of our educational mission,鈥 said Jeanette Henderson, ecosystem preserve program manager. She explained that student employees from a variety of fields serve in land management and educational programming roles.

鈥淚 want you to care about God鈥檚 creation,鈥 she said of her approach to working with students in different majors. 鈥淲orking here might shape your future profession. It might influence the habitats of your daily life, how you raise your future children to care for creation or how you vote on environmental issues.鈥

Randy Van Dragt, professor of biology and the preserve鈥檚 director, sees the protected land as a Calvin distinctive. 鈥淥f all the colleges in Michigan we鈥檙e really among the few that have one preserve, not to mention two,鈥 he said (also referencing Calvin鈥檚 off-campus聽).听

Besides education, Van Dragt says the on-campus preserve is also a place for respite. 鈥淵ou don鈥檛 have to go out there to study,鈥 Van Dragt said. 鈥淵ou can just go out and take some relief from engaging the natural world, which is well established as psychologically beneficial.鈥

Van Dragt makes it clear that there is still work to be done in maintaining the preserve鈥攊n fact, there always will be.

鈥淟iving systems change,鈥 he explained. 鈥淏ecause it鈥檚 an urban preserve, it has a lot of pressures on it to change. Take invasive plant species, which are often associated with disturbance, we have a lot of problems with those. And that means that it costs; there are real expenses involved in retaining a diversity of habitats and not having them homogenize under the influences of invasive species and other things.鈥

鈥淚n order to keep these habitats, we have to do management鈥攁ctive management,鈥 Henderson echoed. 鈥淚t takes funds, and it takes time and it takes skill.鈥

The Towsley grant is a significant step in funding the preserve and interpretive center. Students, faculty and staff will continue to provide the time and skills necessary to run this unlikely gem鈥攁 multifaceted urban preserve right here on Calvin鈥檚 campus.

鈥淲e get to share this space with God鈥檚 creation, and study it and relax in it,鈥 Henderson said. 鈥淣ot every college campus has these opportunities.鈥
